A. Calculate the concentration of sugar in this solution using the volume percent equation. For the purpose of this exercise, it can be assumed that the weight of the drink mix is 0.00 g. The volume of the solution is 3 and 1/3 cups. Calculate and record the volume percent (g/mL). (Note that 1 cup = 236 mL). Volume %=Volume of Solute / Volume of Solution ×100% I used 1/2 cup of granulated sugar and 1/2 tsp of the drink mix, and 3 cups of water. B. Calculate the concentration of each diluted solution using the equation below and the volumes in Table. C1V1=C2V2 Where: C1=concentration of stock solution V1=volume of stock solution C2=concentration of diluted solution V2=volume of diluted solution (This is all the information that I have)

I need to make a solution containing 0.025 grams per liter. However, I do not want to weigh 0.025 grams and put this in one liter of solvent. I want to make a stock solution of 0.25 grams in 500 ml of solvent and take a unknown aliquot and dilute this in 500ml of solvent instead of 1000 ml of solvent. How do I calculate the volume of aliquot from the stock solution to achieve a final concentation of 0.025 grams per liter? What is the proper equation(s) required to figure out the proper aliquots required?
PLEASE ANSWER ONLY NUMBERS 4 AND 5 Shan wanted to extract 3.12g of a new compound from 150mL of water using chloroform. She determined that the solubility of the compound is 0.019g/L and 0.276g/L in water and in chloroform, respectively. Determine: Kd value of the compound between chloroform and water. Amount of the compound that would be extracted if Shan performed a one-step extraction using 75.0mL of chloroform Amount of the compound that would be extracted after the first step if Shan performed a two-step extraction with 37.5mL of chloroform each Amount of the compound that would be extracted after the second step Percent efficiency of the two-step extraction compared to the one-step extraction
Hi, Can you please help me how to do thai question? Thank you! Prepare 100 ml of 1.0 M ammonia solution by diluting 25% ammonia solution (ρ = 0.910). How much should you pipette 25% ammonia into a 100 ml volumetric flask when making the solution?
A real-life problem of permeability: The 100-mile Leadville CO ultramarathon (elevations from 9200-12,600 ft) is being held on a very hot day and you are running the medical tent. A runner is brought in unconscious and with severe dehydration. You have Nursing Assistants that know how to do IV’s, but you have to decide what to give the ailing runner. Your choices (all in sterile IV bags) are: a) 0.15 M NaCl in sterile water, b) 0.3 M NaCl in sterile water, c) 0.3 M glucose in sterile water, and d) pure, sterile H2O. Which would you choose and why? (Include the normal osmotic concentration of blood plasma in your answer.) What would happen to the runner if you gave them the other 3 options?
Main Goal: Convert the experimental glucose concentration from mM (millimolar) to g/100 mL. Take the 1/100 dilution factor into consideration Molarity will open the doors for you to get to grams. Once at M assume 1L of solution. (Hint: this will help you when converting from M to moles) You will also need to calculate the molar mass of glucose which has the formula C6H12O6 There are 5 steps in total Task 1: Write a step-by-step guide with key words for the students on how to do these calculations. Ensure the steps are clearly written and easy to follow.
It is known that acid content has a major effect on theflavor of vinegars, but most cheaper vinegars are diluted similarly to 5% acidity Wt./vol. % is equivalent to gsolute per 100mL solution (so 5% is equivalent to 5 g acid/100 mL solution). a.) First, calculate the approximate molar concentration of acetic acid in the 5% wt./vol vinegar. b.) Next, calculate the expected molarity of acetic acid in the solution upon dilution by a factor of 5. Thank you!
